Title: Improvements in apparatus for elevating a progressively decreasing stack of sheets or the like
IPC: B65H1/18
Filed: 1937-05-01
Abstract: 487,277. Feeding sheets. NEW JERSEY MACHINE CORPORATION. May 1, 1937, No. 12488. Convention date, May 11, 1936. [Class 100 (i)] In apparatus for automatically elevating a decreasing stack of sheets or the like of the type having a vertically movable support for the stack, elevating mechanism and releasable means for disabling the elevating mechanism, and means controlled by a feeler moving into and out of contact with the top of the stack for releasing the elevating mechanism, the releasing member is pivoted on a common axis with an oscillatable member having a radial arm connected with a feeler intermittently movable into and out of contact with the top of the stack, so that the arc of movement of the member progressively increases as the stack decreases in height, the member having also a radial abutment engageable with the releasing member to swing it about the common axis to release the elevating mechanism when the height of the stack falls below a certain level. The stack of labels 5 is held in a hopper 6, whose walls extend above the normal height of the stack, and is supported by a table 7, periodically raised by rack and pinion 9, 10, operated by pawl 13 and ratchet 12. The pawl carrying lever 16 is oscillated against the action of a spring 22 by a cam 18, but is normally restrained by a pendant 28, which places a shoulder 32 under a plate 21 on the lever 16. A detent pawl 24 for the ratchet 12 is carried by a pivoted hand lever 25. The lever carries a pin 26 adapted to engage a projection 27 on the pawl 13, so that it can be operated to put both pawls out of action and to permit manual adjustment of the table. A gravity-operated feeler 45 is raised from the stack 5 by a link 41, bell-crank lever 38 fast to a shaft 34 and roller 39 and cam 48. The axle of the cam 48 carries also an arm 49 which reciprocates a sliding carrier 54 for a suction head 56. The head 56 is vertically reciprocated in the carrier 54, so as to lift a label from the stack, carry it across one adhesive applying roller 60 and stick it to an article c. The feeler 46 is moved in synchronism with the suction head so that only one makes contact with the stack at once. As the oscillations of the feeler and consequently of the axle 34 increase with diminishing height of the stack, a yoke 36 pinned to the axle 34 finally makes contact with and swings a member 33 loose on the axles. The member 33 carries a screw contact 35 which engages and swings pendant 28, thus releasing the elevating mechanism. When the top of the stack reaches its normal height, the yoke 36 ceases to engage the member 33 and the shoulder 32 swings back to restrain the lever 16.

Title: An Improved Machine for Preparing Grinding and Polishing Intaglio Printing and other Cylinders.
Inventor: MILLS THOMAS JOSEPH
IPC: B41C1/18
Filed: 1916-09-05
Abstract: 103,782. Mills, T. J., and Morris, E. T. Sept. 5, 1916. Rollers, treating.-Comprises a machine for grinding and polishing intaglio printing and other cylinders, which may be provided with a turning- tool. The machine is of the kind in which the cylinder is rotated in contact with the flat face of a grinder which is traversed along the cylinder and at the same time moved to and fro transversely and rotated on an axis at right-angles to that of the cylinder. The invention resides mainly in the means for supporting and driving the grinder. The grinder 10 is secured in a cup, the stem 13 of which is mounted for rotation in the socket 14 of the slide 5, Figs. 3 and 4; the slide is carried in a frame 3 mounted on the shaft 1 between brackets 2, which stand up from the saddle m. The shaft is supported in bearings at the ends of the machine, turns freely in the brackets and in the frame 3, and has secured to it eccentrics 9, bv which the slide is moved to and fro in the frame, and a screw-wheel 19 by which rotary motion is imparted to the grinder through the wheel 18, spindle 17, and bevel-wheels 16, 15. The weight of the grinder may be counterbalanced in the manner shown, and a worm gear arrangement 23, 25 is provided whereby the grinder may be raised clear of the cylinder, held at a fixed height for grinding, or allowed to bear freely upon the cylinder. The cylinder is driven by chain gear from the shaft k and the saddle m, which may be provided with a turning-tool o, is moved to and fro on the bed n by a screw p driven from a vertical shaft 44 by bevel-gear q, r and a clutch controlled by a tappet rod. The nut on the screw engages between lugs on the saddle and may have its periphery toothed to form a wheel for engagement with a worm on a cross-shaft provided with a hand-wheel whereby the saddle may be traversed by hand. The shaft k is driven from the electric motor l through a three-speed gear having a combined bevel-wheel 40, spur-wheel 41, and spurwheel 42 movable along the shaft k. In the position shown, the drive is through the bevelwheel, the vertical shaft 32, and the worm gear 31, 33; endlong movement of the combined wheel brings first one and then the other of the wheels 41, 42 into gear with corresponding wheels on the shaft 37, which is driven from the motor shaft by spur gear. For the low-speed traverse for turning, the vertical shaft 44 is geared to the shaft k by worm gear; for grinding and polishing, the wheel 49 is moved endways, and the drive is transmitted through the bevel-gear 46. The endlong movement of the wheel 49 brings it into engagement with the wheel 50, from which motion is transmitted to the shaft 1 by spur and chain gear. The shaft c of the cylinder runs in bearings b having readily removable caps b<1>.

Title: Treatment of refuse material to recover paper fibres therefrom
IPC: D21B1/32
Filed: 1975-03-26
Abstract: 1498706 Recovering fibre from waste material KEBE ANSTALT FUR VERTRIEB VON ANLAGEN FUR KEHRICHTBESEITIGUNG 26 March 1975 [23 April 1974] 12768/75 Heading D1F [Also in Division B2] Paper fibres are recovered from solid refuse material by screening it to separate fine and coarse components (which latter include the fibres), macerating the coarse components in water so that the fibres form a suspension therein, separating the fibres from other materials in suspension, removing the paper fibres and, optionally, heating them (to reduce their water content) as by burning others of the coarse materials. The water is recycled and the fine components may be recovered to form compost. In the operation of the apparatus represented in Fig. 1, domestic waste is fed continuously at 2 into and through a rotary screen 1 through which fine particles, at least partly organic, pass to a recovery conveyor 3. Coarse materials travel on path 4 and into a perforated cylindrical rotor 5 rotating partly immersed in water (which may be heated) in a tank. Remanent coarse materials move on to a recovery path 7 but paper fibres and other fractions dispersed in water pass through the rotor wall thence through a duct 8 to a separating or densifying unit 10 (water from which returns to the tank via duct 9) and the paper fibres are recovered at 12. Surplus water may be removed from fibres by means of a rotary sieve filter, vibrating chute or squeezee rollers (not shown) or by combustion of materials from path 7. In the apparatus of Fig. 2, the rotating rotor 5 receives material from a hopper 22 and discharges the coarser parts from an outlet 5A into section 6A of tank 6 (separated by a perforated baffle 6B from a section directly beneath rotor 5) whence it is recovered from the sloping bottom thereof as by use of a rake 24. In a modification, Fig. 4, water from duct 9 is discharged directly into rotor 5 but (in both forms of apparatus) a part may be discharged over the rotor; a portion 5B of the rotor allows the material to be raised, above the water level in tank 6 prior to discharge, as by means of a group of vanes and/or a wing or group thereof on the interior of wall (of) 5B or along the entire rotor 5 (which also facilitate the discharge of the material). The feed of material along the rotor may be assisted by water jet as adjustably inclining the rotor axis or rotor contour and/or projections therein.

Abstract: 131,119. Yates, R. Aug. 7, 1918. Mechanical telegraphs.-A cancelling-arrangement for mine and like signalling apparatus which cancels the " active " signal when the engine moves to comply, but allows special signals, such as " men " or destination signals to remain exhibited until the engine comes to rest, comprises an arm C moved over and co-operating with contacts E, F and also serving to move, by engagement with tappets S, S<1>, a sliding rod I which carries an insulation piece K and a bridging contact T co-operating with spring-pressed brush contacts in a circuit which is thus opened or closed according to the position of the rod I. Signals are given on a known type of indicator in the usual way, and when a pause is made at a special signal, say 3 (men) a corresponding indication is given on a separate indicator by a relay M closing a local circuit. The arm C rests, when the engine is at rest, on contact F, and rod I is in position breaking circuit at K. When the engine moves, the arm C is moved, by any suitable connexion, and in passing over contact E closes the circuit of a relay L, cancelling the " active " signal. Further movement of the arm operates the rod I so that contact T prepares the circuit of a cancelling relay N. This circuit is completed, and the " men " signal cancelled, when the arm C again comes back to contact F as the engine comes to rest. The rod I is then moved to break circuit at K by a slight further movement of the arm C taking place after contact F has been reached. A contact is provided at P, held open when the indicator is at zero, so that should a signal to stop be given whilst the " men " signal is showing and the engine still running, the closure of contact P energizes a relay O which move, the rod 1 to break contact at K before the active signal is cancelled by the arm C passing over contact E. This prevents the " men " signal from being cancelled when the arm C reaches contact F in compliance with the " stop " signal

Horizontal and vertical synchronizing pulses obtained from a monitored television receiver at terminals 26 and 28, Fig. 1, are compared with corresponding pulses obtained from a reference receiver at terminals 22 and 24 with the aid of coincidence gates 30 and 34 and the gate outputs are applied to control an indicator or recorder 42 by way of a further coincidence gate 38, multivibrator 40 and integrator 41, the arrangement being such that an indication or record is produced only when both the horizontal and vertical synchronizing pulses from the two receivers are in phase. The arrangement is intended for audience survey purposes and serves to indicate whether a monitored receiver is tuned to receive the same channel as the reference receiver. The horizontal sunchronizing pulses may be derived from the picture tube cathode circuit or horizontal scanning oscillator whilst the vertical synchronizing signals may be derived from the vertical scanning oscillator. Reference is also made to means (not described) for receiving the signals from the monitored receiver remotely. Detailed transistor circuits for units 30, 32, 34, 36 and 38 are described with reference to Figs. 2-4 (not shown). Multivibrator 40 comprises a circuit as shown in Fig. 5 in which the multivibrator pair 134, 136 is reset after being triggered in response to a pulse at terminal 128 by a unijunction transistor 164 which is itself triggered after a time primarily determined by C.R. circuit 166, 168.

Valve plate 32 has a port 41 above the liquid level (Fig. 3, not shown) to draw drying air through the filter cake and at least one port 44 through which suction is applied to immersed sectors, and port 44 is provided with a valve 45 to vary the degree of suction. As shown valve 45 is a radially movable rod intersecting port 44. An alternative valve would allow a variable amount of air to leak into port 44 from the plate periphery, or valve 45 may be replaced by a rotatable, slotted valve stem. Plate 32 also has means 42, 43 whereby compressed air blows dried filter cake from successive sectors, and scrapers may also be provided. Means 42, 43 comprises a port through plate 32 with a tube 43 extending radially into it and closing the rear side of the port. Plate 32 and housing (31) may be of polyurethane or rigid PVC while plate (33) is steel, this combination having a self-sealing effect. Arrangements wherein plates 32 and (33) are both polyurethane or where plate (33) is polyurethane and plate 32 metal are described as less effective. When worn on one side, plate 32 may be transferred to a similar rotary valve at the other end of the shaft, where its other side will engage a wear plate, tube 43 being then reversed. Figs. 1, 2 (not shown) illustrate a prior art valve.
